J-Trace PRO is an advanced debug probe that supports Arm's advanced tracing features of Arm Cortex cores. It can capture complete instruction traces over long periods of time—thereby enabling the recording of infrequent, hard-to-reproduce bugs. This is particularly helpful when the program flow "runs off the rails" and stops in a fault state.

In combination with our toolchain independent debug software Ozone and the extensive example project library, including the most popular target devices, our J-Trace PRO user gets the best possible trace experience.

Features

J-Trace PRO offers an extensive featureset fulfilling any requirement a J-Trace PRO user might have. The most prominent features that make this trace probe the leading trace probe are as follows:

Free stand alone debugger Ozone can be used with any tool chain to enable tracing

Unlimited Flash Breakpoints

Trace Reference Board included for quick and easy first steps

Fanless design

Streaming Trace

One of J-Trace PRO's main features is the so called Streaming Trace. With this feature J-Trace PRO can process instruction trace data sent from the target device in real-time fashion using trace pins. That way the user knows exactly what the target device is and was doing at any point in time. This does not only enable a deep insight in any application running on the target device but offers also additional powerful debug strategies that can be applied.

Real Time Profiling

Real Time Profiling provides visibility as to which instructions have been executed and how often—so hotspots in an application can be addressed and optimization opportunities identified. These profiles can later be exported using e.g. Ozone debugger for documentation and analysis purposes.

Real Time Code Coverage

Real Time Code Coverage helps engineers have visibility over which parts of the application code have been executed.

To support the application development on embedded systems SEGGER offers the full array of development tools and software. To support the application development on embedded systems SEGGER offers the full array of development tools and software. Starting with its own IDE Embedded Studio, debugging with the industry-leading J-Link, scheduling the application tasks with the zero-latency RTOS embOS, tying in Microcontroller peripherals via its Middleware, and finally programming the software on the target through its own flash programming tool. All these tools are part of a closed-loop development process. Each tool has to prove its reliability in SEGGER's every day work. As an example the core of the J-Link firmware is based on embOS and SEGGER's own middleware. These components have proven their reliability in more than 450,000 J-Links in the market.
SEGGER constantly improves and extends its product portfolio. Among the most recent additions are the compression tool emCompress, the debug probe J-Trace PRO and the real-time analysis tool SystemView. The development process for application developers is supported by the development environment Embedded Studio and the J-Link debugger. The development of applications can be based on the real-time operating system embOS, the middleware for file system, IP stack, USB as well as on the security components emSSL and emSecure. Finally the portfolio offers programming solutions for prototyping, mass production and in-field-service.
All products follow the philosophy, that the own tools are used within the company. As an example, the market leading J-Link is based on the RTOS embOS and SEGGER's middleware. These SEGGER products can prove their reliability day in day out at SEGGER and SEGGER's customers.
